TestNG - 构造函数上的@Test

Question

I don't have the newest version of TestNG, and I have option to add @Test on constructor, java docs

 @Target({METHOD, TYPE, CONSTRUCTOR}) public @interface Test {

I didn't find any clue on usage in docs or searching online

@Test Marks a class or a method as part of the test.

When/Why @Test can be define on constructor? is it for internal purposes only?

I saw that CONSTRUCTOR was removed in latest TestNG version, but I didn't find why.

Answer 1

See issue " Remove irrelevant "targets" for TestNG annotations ": The target CONSTRUCTOR had no functionality in older versions, because constructors were not seen as test methods. That's why the target was removed later.
